For those of you requiring context for the disturbingly violent cross-network brawl between Conan O'Brien, Stephen Colbert and Jon Stewart you're about to witness, a feud recently erupted between O'Brien and Colbert over their dueling claims of having made Republican presidential hopeful Mike Huckabee candidacy viable (ignoring, of course, The Chuck Norris factor).

The disagreement spiralled out of control into a tragic tangle of responsibility-claiming and show disruptions that spilled onto all three hosts' sets last night, culminating in the Rambo-quality atrocities unflinchingly documented by O'Brien's Late Show cameras; proceed on to the video only if you're sure you're equipped to handle four punishing, uninterrupted minutes of Louisville Slugger bludgeonings, the gruesome torching of pasty comedian flesh, and a near-beheading by the razor-sharp blades of a pair of hockey skates.
